Abstract:
Objective To study the rule of breaking Ferula fukanensis seed dormancy under low-temperature and content changes of endo-hormone.Methods The seeds were treated with stratification under 4 ℃ and germinated under 20 ℃.The content of endo-hormone,such as Z,GA_3,IAA,and ABA,was mensurated by HPLC.Results The seed germination rate achieved as high as 14% in 20 d and more than 60% in 40 d.Among breaking the seed dormancy,the content of endo-hormone was decreased gradually,while the rate of GA_3 and ABA was increased quickly in 10—20 d under 4 ℃ stratification.ConclusionThe stratification under 4 ℃ could break the seed dormancy.The rate of GA_3 and ABA is a pivotal factor of the seed dormancy.The endo-hormones IAA and Z have the significant effect on seed germination.
